Application filed June To 'all whom it may con-cernfl Be it known that we, Pnrnirrn A. Das- LAURIrns and LOUIS P. DESLAURIERS, citizens of the United States, residing at St. Paul, in thecounty of Ramsey and State of Min- 1 nesota, have invented certain new and use- 1 Concrete Ceilings {and Supporting-Columns,

ful Improvements in Means for Forming of whichthe following is a specification.-

Our inv'ention relatesto improvements in means for-forming aconcrete ceiling and supporting columns, and consists particularly in'inipr'oved, expansible molds for the ceiling and adjacent portions of the columns. Tothis end our invention consists in the features of construction and combination hereinafter particularly described and claimed.

In the accompanying drawings forming part of this Specification, Figure Iis a plan view of one form of our invention, Fig. 2 is a side elevation of the same partly broken I away, Fig. 3 is a perspective view of a term plet frame forming part-of our invention, Fig. l 1s a detail of an adplstment for overlapping plates embodied in the invention,

Fig. 5 is a plan view of a modified form of our invention, 6 is a perspective view of a; concrete cast ng formed by. the mold shown in Fig.5, Fig. 7 is a section on line a I iv-wot Fig. 5,. Fig. 8 is a plan view of-a.

supporting plate used in connection with the mold shown in Fig. 5,. Fig. 9 is a perspective view of a modified form of mold for round columns, Fig. 10 is a detail oat a clamping ring to be used in connectionwith v the mold shown in Fig. 9, F1g.,11 1s a per view of a beam mold, Fig. 12 1s aspective perspective view of amoolified form of mold to be used in connection with a round column, Fig. 13 is a perspective view of. plates forming part of the mold shown in Fig. 12, and Fig. 14 is a section on line yy of Fig. 12.

In the drawings A represents a mold or casing for the top of a square column. In

order to make the mold expansible for differ ent sizes of columns we construct the same of a series of platesf2 and 3 adjustably-connected by bolts 4. The plates 2 form the corners of the column and the plates 3 are bent outwardly at right-angles thereto to. support an mtermedlate mold 5 for the ceiling beams. The mold 5 is composed of right-angle plates ad ustably connected by bolts as shown m Fig. 2 so as to be expansi- Specification of Ietters' l'ateiit. Patented Dec. 28, 1909.

ble in cross section. The mold 5 is inclosed by a templet frame 7 composed of bars adjustably connected by bolts 8. Secured to the sides of each mold 5 are brackets 9 having flanges 10 extending outwardly from above the mold to form supporting ledges for the ceiling mold plates 11 which are preferably corru ated as shown. Supporting the molds 5 1s a templettram'e 12 consisting of righbangle bars adjustably connectedby bolts 13. i

In Fig. 4 is shown a form of adjustable connection for the plates of themolds, con sisting of a bolt 1 1 passing from one plate through a slotted opening in the other plate,

the slotted opening being covered by a cap plate 15 and held in position by a nut 16 upon the bolt. Thus the concrete will be prevented from working through. the slotted OPBIHIIQ. p

In Figs. 5 to 7' is shown a'modifiea form of our invention. In this form the mold .1 consists of cornerplates 17 adjustably connected by bolts 16* to the inner ends of the beam mold 5-, said beam molds being shown conventionally inFig. 5. The plates 17 are bent outwardly at their upper ends to form flanges'lS upon which is designed to rest ceiling mold plates 19. o show in Fig. 5

" the molds A and 5 proportioned to construct different widths of ceiling beams and in Fig. 6 is shown a column top and connected ceiling beams formed by the mold shown in Fig. 5. The mold A in Fig. 5 is inclosed blovv the' beam molds 5 by a suitable tem-.

plet' frame such as the templet frame 20 shown in Fig. 10, consisting of two semicylindrical bars connected at their ends by bolts 21. i y

.In Fig. 9 is shown a mold forthe upper end of a round column justbelow the crown consisting of plates 22 bent at their lower [ends to form a round column and at their ends to form a s uare, the plates being connected by ang e irons 23. The branch molds 5 for the ceiling beams are shown provided with-downwardly inclined inner ends extending inside the top of the column mold, the remainder of the column top being formed by the plates 25 connected with the branch molds and with the column mold as by means of bolts 26. By dotted lines we'show a squat; templet frame inclosing the top of the column mold and a round templet frame inclosing the lower ,end of the mold.

In Fig. 11 is shown a beam mold 27 which, it will .be noted, corresponds in construction to the'mold 5 and which in operation constitutes an extension thereof. The mold 27 is inclosed by a templet frame 28 corresponding to the templet frame 7 and with brackets 29 corresponding with the brackets 10 for supporting the ceiling plates 11. Thus by combining the column and crown molds with the beam molds and supporting thereon the plates 19 and ceiling plates a metal mold is secured for the entire ceiling and crowns ofall the supporting columns. By supporting the flat plates 19 at the corhem of the molds A a support is ,secured for the ceiling plates 11' thus allowing ordinary sheet metal plates to beused for the ceiling mold without having to cut their ends to fit the column molds. I In Figs. 12 tol we show a non-expansiblemold 311-for thetop of a round column formed with an outwardly extending flange 32 to receive aplate 33 corresponding to the plate'1'9.. The plates 33 form a rectangular -mold -for the'ceilingat the top of the column. and a support for the ceiling mold plates l1.-

Among the most important advantages of our invention is the securing of mold forms for the crowns of the columns which wil allow ordinary sheet metal plates wit square out ends to be used for the ceiling molds without necessitating the cutting off of said plates to conform to the tops of the columns. This we accomplish by means of the plates 19 or 33 suitably supported from the column top mold and over which plates 19 or 33 the ceiling mold plates 11 overlap Of course, it will be understood that-the mold plates will be supported byordinary scaffolding 35 as partly shown in Fig. 12-.

- We claim:

1. Means for forming a concrete ceiling and connected columns, comprising a sheet metal mold shaped to form the top of each column, an outwardly bent supporting flange formed'on the upper edge of said mold, and plates entirely surrounding said mold and'overlapping said flange for the purpose of moldingthe adjacent portion of the ceiling.

2. Means for forming connecting concrete columns and ceiling, comprising a sheet with 4. Means .d'or forming concrete ceiling and connecting columns, comprisinga longitudinal split "casing for each column top, means securing the same closed, outwardly eirt Eh dmg brackets arranged in connection etop of saidcasingfl supporting mold plates supported upon .id brackets, and ceiling. mold plates ove'lapping said supporting mold plates.

5. Means for formin. concrete ceiling and supporting columns comprising a longitudinally split casing for each column top, means securing the same closed, beam molds extending outwardly from opposite sides of said casing, brackets extending outwardly between said column top and beam molds, mold plates supported upon said bracket.- and ceilingmold plates overlapping said mold supporting plates.

6. Means for forming a concrete ceiling and supporting columns, comprising an expansible casing for the top of each column, an expansible templet frame for said casing, expansible beam molds extending outwardly from opposite sides of said casing, and an expansible templet frame for said beam molds, brackets extending outwardly from said casing intermediate of said beam molds, brackets extending outwardly from the opposite sides of said beam molds, and ceiling mold plates supported by said brackets.

. In testimony whereof We afiix our signa tures in presence of two witnesses.
